Probing Fermionic Condensates by Fast-Sweep Projection onto Feshbach Molecules

Other Condensed Matter 2008-12-08 v2

Abstract

Fast sweep projection onto Feshbach molecules has been widely used as a probe of fermionic condensates. By determining the exact dynamics of a pair of atoms in time varying magnetic fields, we calculate the number of condensed and noncondensed molecules created after fast magnetic field sweeps from the BCS to the BEC side of the resonances in 40^{40}K and 6^{6}Li, for different sweep rates and a range of initial and final fields. We discuss the relation between the initial fermionic condensate fraction and the molecular condensate fraction measured after the sweep.
